Our fintech mobile apps

Team up with experts in finance mobile app development
Our services are tailored to meet the needs of startups and corporations looking to develop a functional, secure, and usable finance app
Finance isn’t as simple as plugging in numbers on a spreadsheet. Financial apps have to be able to display large amounts of data and include complex user flows. Despite the complexity, fintech must make daily financial operations accessible and user-friendly for everyone. And that’s exactly how we design finance apps.
Your app might require integrations with different financial APIs. Some of these APIs are needed to help you verify user identity, some to enable stock trading, and some to move money internationally. With our large expertise in fintech, we don’t only integrate your app with all the needed services. We help you define what services you need to integrate with.
At Surf, you get a chance to work with some of the top fintech app developers out there. We specialize in both native and cross-platform technologies. Our native apps are written in Swift (for iOS) and Kotlin (for Android) and we use Flutter to develop apps that run on both platforms. But what's even more important, we know how to build effective work relationships with our clients that last for years.
When it comes to money and personal data, QA testing isn’t just “nice-to-have” — it’s a must-have. Minor bugs can undermine your app’s credibility. To make sure your banking or finance app is functional, secure, and usable, we cover 80% of your code with auto and unit tests and run up to 50% of test scenarios manually.
There can be many areas of vulnerability or risk in financial mobile app development. After all, the financial industry is hackers' sweet spot. To minimize the probability of hackers attempting to access personal, financial, and banking information in your app, we write secure code and put your application through rigorous assessments.
If your time to market is crucial, we can speed up mobile application development for fintech by building iOS and Android apps simultaneously. We have open code standards, so developers can jump into a project and get up to speed pretty quickly.

What our Clients say

There was no backend development expertise in our bank, so the work on the server-side fell on different contractors. In the process, we realized that it would be much better to let Surf develop the entire application because they have deep analytics and understanding of our business processes
Dmitry Malykh, CPO and Head of Electronic Business Department
We announced a tender for the development of a Flutter banking app, then we studied the portfolio of companies, relevant experience, and cost. What I liked most about Surf was that it was not too lazy to make a demo from layouts and offered us a reasonable price. We did a really great job as a single product team
Andrew Davydov, Head of MobileThe most impressive thing about Surf is their great expertise in mobile development and excellent teamwork. It is also worth mentioning their extensive banking experience, as well as their clear understanding of fintech projects, their specifics, and typical UX aspects. Last but not least, they place a high priority on app security.
